Is it alright to have spaces in directory (folder) and file names?
In theory yes, in practice don’t. There are some applications, and some scripts (including some that I wrote) that misbehave if a space is encountered in a filename or path. I know that spaces are “normal” in Windows, but it is good to get out of the habit when using Linux. Use underscores “_” or dashes “-” instead. For example, “/root/my-applications/”. After all, Internet URLs do not allow the space character, so it is consistent to have this restriction for local “URIs” (pathname/filename). Another trap for the unwary is case. That is, “A” is different from “a” in Linux. Linux folder and filenames are case-sensitive. While I’m thinking of traps for the Linux newbie, here’s another. Say that you open a Rxvt terminal window in directory /root/ and in that directory you have an executable program that perhaps you have downloaded. let’s call it “Demoexe” — I’ve even given it a capital letter!
